This is the genuine SEIKO PROSPEX SBDC105 strap. (Watch body not included) Lug width: 20mm As shown in the images, there are many scratches on the stainless steel parts. There is wear on the strap pattern and slight deformation when viewed from the side due to friction from use of the 5th and 6th strap holes from the 6 o'clock position of the watch. There appear to be no cracks, tears, or splits, but I may have overlooked something, so please refrain from purchasing if you are concerned. The silicone appears to be highly durable. Compared to the genuine straps of previous models, it doesn't attract dust, is flexible, and is useful for summer when you sweat, water-related work, water leisure, camping, mountain climbing, etc. How about it for work or leisure? Due to the condition, please consult about the price. Thank you.
